Sending to the list is not a bad thing. We know the OP sent to the list,
because his post appeared on the list :-)

The question is whether he BCCed a bunch of regulars or not.

Unfortunately I deleted the email so I can't look at the headers, but
nevertheless I can categorically say that it didn't come from the mailing
list, because the python-list at mailing list doesn't have my
address. I've always read this though the newsgroup.

I do still have the relevant mail logs:

Mar 25 03:08:36 ando postfix/smtpd[24188]: connect from[]
Mar 25 03:08:37 ando postfix/smtpd[24188]: 2093D1204E2:[]

Mar 25 03:08:38 ando postfix/smtpd[24188]: disconnect from[]

I'm not an expert, but to me that looks pretty convincing that the email
came directly from Google, not from the mailing list. Am I wrong?

Maybe you weren't one of the people he BCCed :-)

“Cheer up,” they said, “things could be worse.” So I cheered up, and sure
enough, things got worse.
